1) Intuitive LCD display and control panel bring convenience to theoperation;2) Original imported brushless motor is characterized by great torque,low noise,non-vibrations as well as accuracy;3) Alternative input supply voltage: AC100-110V or AC220-240V;4) Multifunctional foot switch is not only handy to operate but alsoagainst cross-infectioncaused by the contact between hands and the device;5) Adjustable rotation speed, torque, coolant flow and forward/reverse,which can meetvarious demands during implanting process;6) 10 types of reduction contra angles are able to be selected in order tomeet variousclinical demands;7) 10 kinds of program settings. Each of which allows setting updifferent values of rotationspeed, torque, coolant flow, forward/ reverse and reduction ratio.
